ERK’s global reach
32 Licensees all over the World
ERK transfers know-how and grants licences to plant manufacturers and
engineering companies. The technological support within the scope of the licence
and know-how contract enables licensees to manufacture state-of-the-art corner
tube boilers and combustion systems that have proven themselves in operation.

2. Case study 1 – Biomass Gasification
ERK’s Biomass Gasifcation
• >100 references for biomass gasification plants (1-70 MWth)
•
•
Simple scale-up to 40 MWel
>40 MWel plants possible, but unusual for biomass; gasifier adaptation
necessary

4. ip tube
ip tupe – An example of R&D by ERK
Main Characteristics:
 Increase of heat transfer
 Increase of heat transfer efficiency
 Reduction of the fouling (inside/outside)
Advantages
 Material saving &costs reduction
 Foot print reduction
 Operating costs reduction
 Environment pollution reduction

Heat transfer
 Macro structure increases the α value
inside on the tube side and on the shell
side
 Macro structure increases α by factor 1,5
to 4,5 depending on the macro structure
 Several structures are already well proven
 Over 150 projects with ip tubes are already
realized
